Material pick-up area calibration system and pick-up system of cutting machine and calibration method of material pick-up area calibration system

Abstract

The invention relates to the field of automatic calibration, and discloses a material pick-up area calibration system and a pick-up system of a cutting machine and a calibration method of the material pick-up area calibration system. The material pick-up area calibration system comprises a projector, light sensors and a controller. The projector is arranged above a pick-up area and used for projecting boundary images to the pick-up area. At least three light sensors are arranged on the boundary of the pick-up area, the different light sensors are arranged at different boundary positions of the pick-up area and used for detecting light brightness, and when the detected light brightness exceeds a preset value, signals are transmitted to the controller. The controller is used for adjusting the projection direction of the projector till the signals from all the light sensors are received. According to the implementation mode, calibration on the material pick-up area of the cutting machine can be accurately and reliably achieved, that is, the actual boundary positions of the pick-up area can accurately correspond to all the boundary images projected by the projector to the pick-up area, and the problems generated by uncalibration of the boundary positions of the pick-up area are reduced.

Description

technical field [0001] The invention relates to the field of automatic calibration, in particular to a material picking area calibration system of a cutting machine, a picking system and a calibration method thereof. Background technique [0002] An automatic cutting machine is a device that automatically cuts fabrics, the most common fabrics being cloth or leather. At present, the head of the automatic cutting machine cuts the fabric laid on the cutting table according to the pre-made cutting data. After the cutting is completed, the conveying mechanism directly transports it away from the cutting area, and sends it to the material picking area to sort different types of materials. Since there are many kinds of cut materials, when sorting and picking up different materials in the material picking area, it is necessary to distinguish the corresponding positions of the cut materials and the picking area. The operators often confuse the position of each material when sorting,...

Problems solved by technology

In the existing operation method, the manual calibration is generally performed by the operator. Obviously, the error caused by manual operation is relatively large, and it is time-consuming and labor-intensive.
